Roksan M2 power amp has inputs and outputs on both RCA and XLR connectors.
Did you plug the interconnect cables in the input connectors of the amp?
There's a switch between the XLRs and RCAs to select which type of inputs you want to use.
Check if the right one is selected
AAAARG your right DUH!
I cant test again untill Saturday, i'll let you know
